Concrete screw cuts threads into concrete, hollow block, brick, mortar, and concrete masonry units to provide a secure hold without requiring threaded inserts
1022 carbon steel screw has a corrosion-resistant blue R-Blocker coating that meets ASTM B117 specifications to resist 1,000 hours of salt spray
Flat head sits flush with the mating surface when installed in countersunk holes, and the x-shaped Phillips drive prevents over-tightening and accepts a Phillips driver
Ultimate tensile strength is 670 lb. at 1'' embedment depth and 1'' edge distance in 2,730-psi concrete
Use one-fourth or less of listed maximum values for safe working loads (as required by local regulations)
